SYMPLiK EXZELLENZ is a Java program to manipulate table data in Oracle database by using Microsoft Excel file. Unlike Oracle WebADI, More4Apps or other Excel-driven solution, this program does not use Office VBA (Macro) to process the data. It is a pure Java solution incorporated with Apache POI and Oracle JDBC driver to download, upload, insert, update and delete data from Oracle database tables.
Das Problem …
PHP-Scripte werden nach einer bestimmten Laufzeit abgebrochen (normalerweise nach 30 Sekunden), und so funktioniert ein Backup mit diversen Tools nur bis zu einer bestimmten Größe.
Braucht das Script länger als die 30 Sekunden, so wird es vom Server einfach abgebrochen, und man kommt nicht mehr an sein Backup heran. Gleiches gilt für das Wiedereinspielen eines Backups.
Wer einmal ein Dumpfile von Hand in viele kleinere Einzelabschnitte zerlegt hat, um eine Datenbank wieder herzustellen, der weiß genau, wovon wir reden.
MySQLDumper ist die Lösung …
MySQLDumper umgeht den Timeout-Error mit Hilfe eines kleinen Tricks: Er liest nur eine bestimmte Anzahl von Datensätzen aus der Tabelle aus, merkt sich, wie weit er gekommen ist, und ruft sich anschließend selbst auf. Dadurch erhält das Script bei jedem Aufruf wieder die vollen 30 Sekunden und umgeht so den Timeout-Error. Das gleiche Prinzip benutzt MySQLDumper auch beim Wiederherstellen der Daten.
MySQLDumper kann die Daten beim Sichern sofort packen. Auch das Wiederherstellungsscript kann direkt aus dieser gepackten Datei lesen, ohne dass sie auf dem Server entpackt werden muss! Natürlich kann man die Datei auch ungepackt lassen, aber spätestens beim Hochladen eines Backups weiß man dies zu schätzen.
The agimatec tools contain some utilities to enable generation of files, source code etc. from sql files and annotated java classes.
The agimatec-dbmigrate tool is a database migration/script execution framework that can execute sql scripts, groovy scripts and provides a lot of features to assist in database schema migration. (tested with Oracle and Postgres)
Generic Model Organism Database project, a collection of open source software tools for creating and managing genome-scale biological databases. You can use it to create a small laboratory database of genome annotations, or a large web-accessible community database. GMOD tools are in use at many large and small community databases.
SymmetricDS is web-enabled, database independent, data synchronization/replication software. It uses web and database technologies to replicate tables between relational databases in near real time. The software was designed to scale for a large number of databases, work across low-bandwidth connections, and withstand periods of network outage.
log4jdbc is a JDBC driver that can log SQL and/or JDBC calls (and optionally SQL timing information) for other jdbc drivers using the Simple Logging Facade For Java (SLF4J) logging system.
SQL Workbench/J is a free, DBMS-independent, cross-platform SQL query tool. It is written in Java and thus it should run on any operating system that provides a Java Runtime Environment.
It's main focus is on running SQL scripts (either interactively or as a batch), graphical query building or administration of the database is not the focus.
Do you hate starting on a new project and having to try to figure out someone else's idea of a database? Or are you in QA and the developers expect you to understand all the relationships in their schema? If so then this tool's for you.
SchemaSpy is a Java-based tool (requires Java 1.4 or higher) that analyzes the metadata of a schema in a database and generates a visual representation of it in a browser-displayable format. It lets you click through the hierarchy of database tables via child and parent table relationships. The browsing through relationships can occur though HTML links and/or though the graphical representation of the relationships. It's also designed to help resolve the obtuse errors that a database sometimes gives related to failures due to constraints.
Scriptella is an open source ETL (Extract-Transform-Load) and script execution tool written in Java.
Our primary focus is simplicity. You don't have to study yet another complex XML-based language - use SQL (or other scripting language suitable for the data source) to perform required transformations.
Application Ermodeller is a free CASE tool for data modelling which is built in Java. This tool supports conceptual and logical data modelling and in the final step, it allows to create physical model that is specific for particular DBMS.
The basic idea is to support development of database via ER modelling in three levels of abstraction:
* conceptual
* logical
* physical
This separation allows to create database model independent on the particular database system. You may create conceptual model and logical model that are independent on any DBMS. Then, you may generate physical model for each DBMS you will use. Afterwards, physical models allows you to generate SQL data definition for your target DBMS.
Extrema is a powerful visualization and data analysis tool that enables researchers to quickly distill their large, complex data sets into meaningful information. Its flexibility, sophistication, and power allow you to easily develop your own commands and create highly customized graphs.
The Sundog Database Refactoring Tool (SDRT) is an open source (LGPL), DBMS-independent library that eases database development, particularly in an agile environment.
MIGRATEdb will parse an XML file of database changes and load them to the targeted database if they are not already there.
A database change consists of tests to determine whether the change has already been applied and a set of change actions.
dbdeploy is a Database Change Management tool. It helps developers and
DBAs change their database in a simple, controlled, flexible and
frequent manner
SuperQuaiL is a Java SQL query builder. The goal of SuperQuaiL is to help Java developers who code SQL run and create queries easier. Other database tools focus on making it easy to do database administration and it is nice to be able to inspect the database through these tools. PhpMyAdmin, for example, a is nice web front end that you can run from multiple computers, but the interface is clumsy for the developer. For development, building queries is the main task and having a small program that loads quickly is more helpful than having a complicated interface where you can find out almost anything about the database. SuperQuaiL provides nice features to aid in the process of developing queries quick and easy.
DBMT is a easy to use tool for migrating one database from a sources of data (RDBMS, CSV, XML and so on) to another changing database's schema if necessary.
The Pentaho BI Project provides enterprise-class reporting, analysis, dashboard, data mining and workflow capabilities that help organizations operate more efficiently and effectively. The software offers flexible deployment options that enable use as emb
XML to DDL is a set of python programs to convert an XML representation of a schema into a database and vice versa. It can also examine the differences between two databases and emit the ALTER DDL statements required to bring the database up-to-date. This
